Pu`ukohola Heiau National Historic Site

Built entirely by hand in 1791, the Pu`ukohola Heiau National Historic Site preserves the ruin of the last major Ancient Hawaiian temple that was built during King Kamehameha I's reign.

The temple was also the site where Kamehameha unified the Big Island of Hawaii before going on to unify the entire state a few years later.

Today, the park – which is found on the northwestern end of Hawa'ii – is open to walking tours, living history tours, ranger talks, educational tours, and cultural demonstrations provided by the National Park Service.

Don't miss the huge temple mound or take to the ocean and see the submerged ruins of a temple once dedicated to the sharks that swim through it.
